  • Patent number: 4099523
    Abstract: A therapeutic device for applying controlled traction to the neck or lower back of a patient is disclosed. The device includes a pair of relatively rigid, hollow members telescopingly engaging each other. A bladder for the reception of air or other fluid is disposed within the members. The bladder has a stem to permit it to be filled with fluid to a controlled pressure. The fluid pressure acts on the sections tending to cause them to separate axially, but the rigid material prevents radial expansion. Thus, the device provides a controlled amount of traction in an axial direction without a choking radial component.
